When you pitch your spacious Andromeda tent on rough or water-saturated terrain, make sure its floor is protected with the Exped Andromeda Footprint. Clip the Andromeda footprint into place with pole grommets so it stays securely under your tent and keeps the floor safe from sharp objects on the ground. When you pitch the fly of your tent without the body, the Andromeda footprint acts like a ground cloth to keep you off the dirt.
